The Inner Child Keeps on Growing

I've noted in conversation many times in the past that there's a tendency to a sort of 'hive mind' about what you are supposed to like and not like in fandom (though this is maybe not as true as it used to be.) So, just for fun, what important/critically lauded/popular sf books, movies or tv series can you just not get what the fuss is about? Or understand the fuss but don't work for you?

Okay, so here's a starter from me:

I can understand why people consider 2001: A Space Odyssey and Blade Runner to be classics of sf cinema, but try as I might to like them I find them a bit...boring. I'd rather watch Star Trek: The Wrath of Khan or Back to the Future again than either of them.
